Higher threshold (500 mL per six hours or greater) vs lower threshold (less than 500 mL per six hours) at time of aspiration

Mortality (at the end of · adults receiving EN via nasogastric or gastrostomy tube

It is very uncertain whether higher threshold (500 mL per six hours or greater) changes mortality (at the end of compared with lower threshold (less than 500 mL per six hours) at time of aspiration (very low certainty).

Higher threshold (500 mL per six hours or greater) vs lower threshold (less than 500 mL per six hours) at time of aspiration

Pneumonia · adults receiving EN via nasogastric or gastrostomy tube

It is very uncertain whether higher threshold (500 mL per six hours or greater) changes pneumonia (until discontinued or up to 28 days) compared with lower threshold (less than 500 mL per six hours) at time of aspiration (very low certainty).
